RTQ2521GQW - RICHTEK

RTQ2521GQW Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal thermal performance?
  Richtek provides a recommended PCB layout in their application note ANI-23, which includes guidelines for thermal vias, copper pours, and component placement to minimize thermal resistance and ensure reliable operation.
• How do I select the correct input capacitor for the RTQ2521GQW?
  The input capacitor selection depends on the input voltage, output voltage, and desired ripple current. Richtek recommends using a low-ESR capacitor with a value between 10uF to 22uF, and a voltage rating of at least 1.5 times the maximum input voltage.
• What is the maximum allowed voltage on the enable pin (EN)?
  The enable pin (EN) has a maximum allowed voltage of 6V, which is not explicitly stated in the datasheet. Exceeding this voltage may damage the device.
• How do I ensure the RTQ2521GQW meets the required electromagnetic compatibility (EMC) standards?
  Richtek provides guidelines for EMC compliance in their application note ANI-24, which includes recommendations for PCB layout, component selection, and shielding to minimize electromagnetic interference (EMI).
• What is the recommended operating temperature range for the RTQ2521GQW?
  While the datasheet specifies an operating temperature range of -40°C to 125°C, Richtek recommends operating the device within a range of -20°C to 85°C for optimal performance and reliability.
